Counting benefits does not much change the income stagnation story

Lane Kenworthy reports:

A third worry is that the income measure used to calculate median family income is too thin. If a growing portion of GDP has gone to employer benefits, that would help middle-class households, but it wouldn’t show up in these income data.

To address these second and third concerns, we can turn to a more encompassing measure of household income. The data are from the Congressional Budget Office (CBO). The measure includes all sources of cash income. It adds in-kind income (employer-paid health insurance premiums, food stamps, Medicare and Medicaid benefits), employee contributions to 401(k) retirement plans, and employer-paid payroll taxes. Tax payments are subtracted.

We can use average household income in these data as a substitute for GDP per capita. The CBO data set doesn’t tell us the median income, but it provides something quite similar: the average income of households in the middle quintile of the distribution (from the 40th percentile to the 60th). The following chart adds these two series. The story is virtually identical.

He considers some other adjustments too, and this is the final story:
